LISBON (REUTERS) - Pacos de Ferreira coach Paulo Fonseca has signed a two-year contract to take charge of Portuguese football champions Porto, the club said on Monday.

Fonseca, 40, moves to one of Portugal's top clubs after leading unfashionable Pacos to third in the championship last season, their best finish which earned them a Champions League qualifying play-off spot.

"We have reached an agreement with Fonseca, who will become the main team coach," Porto said in a statement to market regulator CMVM (www.cmvm.pt).

Fonseca will have a tough task to live up to the demands of a club used to winning as much as Porto, who have claimed 14 of the last 20 Portuguese titles.
